Abstract

A brake shoe adjustment device for internally mounted shoe brakes is arranged between mutually neighboring ends of two brake shoes which are connected to each other via a tension spring. To minimize parts, size and cost the adjustment device has two mutually opposite spreading elements, each of which is held by one brake shoe end. One of the elements is equipped with a threaded shank that cooperates with a threaded bore of the other element. The elements are axially displaceable by a worm wheel gear which rotates the shank in response to turning by an adjusting tool.
